operator-(ranges::transform_view::sentinel)

friend constexpr ranges::range_difference_t <Base> operator- ( const /iterator/ <Const> & x, const /sentinel/ & y ) requires std::sized_sentinel_for < ranges::sentinel_t <Base>, ranges::iterator_t <Base>> ;	(1)	(since C++20)
friend constexpr ranges::range_difference_t <Base> operator- ( const /sentinel/ & y, const /iterator/ <Const> & x ) requires std::sized_sentinel_for < ranges::sentinel_t <Base>, ranges::iterator_t <Base>> ;	(2)	(since C++20)

Computes the distance between the underlying iterator of x and the underlying sentinel of y.

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when transform_view::sentinel<Const>

x	-	an iterator
y	-	a sentinel

Let current_ denote the underlying iterator, end_ denote the underlying sentinel.

1) x.current_ - y.end_

2) y.end_ - x.current_
